Abstract
An improved bearing construction for a mechanism including a shaft and a relatively rotatable member having an opening receiving the shaft with a cylindrical bearing carried by the member and journalling the shaft, the mechanism being of the type adapted to be loaded generally radially of the shaft. The improved bearing construction contemplates that the opening be elongated in a direction transverse to the direction of loading, that the exterior surface of the bearing is grooved to increase its elasticity, and that there be a thin layer of elastomer interposed between the bearing and the opening to compensate for distortion in the bearing due to dynamic loading.
